Portsmon reports appear to have been broken since an October 2017 update to Python. A thread was posted to FreeBSD forums on 22 October noting a failure: https://forums.freebsd.org/threads/62932/ Mr. Linimon stated, on the thread, that the best way to reach him about this would be via Bugzilla or e-mail. A search in Bugzilla showed no PRs, that I could find, regarding this issue so I'm filing one. Step to reproduce: Use a web browser to open http://portsmon.freebsd.org/portoverview.py?category=sysutils&portname=docker

The error is: The latest Python updated failed. I intend to repair this post-BSDCan 2019 -- mcl link: http://portsmon.freebsd.org/portsconcordanceformaintainer.py?maintainer=ports%40FreeBSD.org
Unfortunately I have not worked on portsmon in several years. If someone wants to take it over, please contact me offline.
